I'll tell ya one thing, you would get a ton of more bang for your buck if you got GTAV over TW101 and RL. Ten fold.
EDIT: Wait, you played through all 5 GTA games and you're not a fan? 5th time's the charm or do you get off on finishing games you don't enjoy?
Not me. 101 is a incredibly unique looking game whereas GTAV is simply another openworld kill people and have sex with prostitutes game. I was sick of it with Age of Conan and I'll never NOT be sick of those games. 101 is charmful looking and not inappropriate. Not to mention 101 looks like it's gonna be one of those games that you replay over and over again years down the road.
No, no it really isn't. There is so many things to do, those two things are some of the least important.
101 looks damn sweet and is quite charming, i don't argue that at all. However, GTAV will give you way more content, including GTA Online. That's just a fact.
